gsa cockroach-darwin-amd64 -f svg -o data.svg --hide-sections
Usage: gsa <file> [flags]
A tool for analysing the size of dependencies in compiled Golang binaries,
providing insight into their impact on the final build.
Arguments:
<file> Binary file to analyze
Flags:
-h, --help Show context-sensitive help.
--verbose Verbose output
-f, --format="text" Output format, possible values: text,json,html,svg
--no-disasm Skip disassembly pass
--no-symbol Skip symbol pass
-o, --output=STRING Write to file
--version Show version
Text output options
--hide-sections Hide sections
--hide-main Hide main package
--hide-std Hide standard library
Json output options
--indent=INDENT Indentation for json output
--compact Hide function details, replacement with size
Svg output options
--width=1028 Width of the svg treemap
--height=640 Height of the svg treemap
--margin-box=4 Margin between boxes
--padding-box=4 Padding between box border and content
--padding-root=32 Padding around root content
Web explorer options
--web use web interface to explore the details
--listen=":8080" listen address
--open Open browserCaution
The tool can work with stripped binaries, but it may lead to inaccurate results.
- Add more pattern for disassembling the binary
- Extract the information from the dwarf section
- Count the symbol size itself to package
- Add other charts like flame graph, pie chart, etc.
- Support C++/Rust symbol demangling in cgo
- Add a TUI mode for exploring details
